In limited-slip differentials, constant high temperatures break down clutch packs and friction modifiers, resulting in reduced efficiency and compromised traction control. The PPE Rear Differential Cover is cast from high-grade A356.0-T6 heat-treated aluminum alloy, a high-strength and thermally conductive material, and adds 0.43 quart of fluid capacity for greater thermal reserve.\u003c\/p\u003e\u003cp\u003eExternal cooling fins pull heat out of the fluid and add impact resistance, while precision-placed internal windage scrapers keep fluid distributed around the gears and cut excessive churning that causes heat, aeration, and parasitic power loss. Together the fins and scrapers form an ultra-strong cross-bracing structure, backed by cast-in gussets that support the differential housing flange. The fill plug sits at the factory level, and both service plugs carry high-temperature neodymium magnets to capture ferrous particles.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePremium A356.0-T6 heat-treated cast aluminum alloy construction\u003c\/li\u003e\n\u003cli\u003ePrecision cast in permanent steel molds for dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eIncreases oil capacity by 0.43 quart for higher thermal capacity\u003c\/li\u003e\n\u003cli\u003eExternal cooling fins lower differential fluid temperature\u003c\/li\u003e\n\u003cli\u003eInternal windage scrapers cut churning, aeration, and power loss\u003c\/li\u003e\n\u003cli\u003eFins and scrapers form an ultra-strong cross-bracing structure\u003c\/li\u003e\n\u003cli\u003eCast-in gussets add housing flange support and rigidity\u003c\/li\u003e\n\u003cli\u003e304 stainless plugs with neodymium magnets and Viton O-rings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrand: PPE\u003c\/li\u003e\n\u003cli\u003ePart Type: Rear Differential Cover\u003c\/li\u003e\n\u003cli\u003eMaterial: A356.0-T6 Heat-Treated Cast Aluminum Alloy\u003c\/li\u003e\n\u003cli\u003eFinish: Raw\u003c\/li\u003e\n\u003cli\u003eCasting Method: Precision Cast, Permanent Steel Mold\u003c\/li\u003e\n\u003cli\u003eDifferential: Ford 9.75 in, 12-Bolt\u003c\/li\u003e\n\u003cli\u003eAdded Fluid Capacity: 0.43 Quart\u003c\/li\u003e\n\u003cli\u003eExternal Fin Height: 9\/16 in\u003c\/li\u003e\n\u003cli\u003eInternal Scrapers: Precision-Placed Windage Scrapers\u003c\/li\u003e\n\u003cli\u003eService Plugs: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003ePlug Magnets: High-Temperature Neodymium\u003c\/li\u003e\n\u003cli\u003ePlug Seals: Viton O-Rings\u003c\/li\u003e\n\u003cli\u003eWarranty: Limited Lifetime\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e(1) PPE Cast Aluminum Rear Differential Cover\u003c\/li\u003e\n\u003cli\u003e(1) 304 Stainless Steel Fill Plug with Neodymium Magnet\u003c\/li\u003e\n\u003cli\u003e(1) 304 Stainless Steel Drain Plug with Neodymium Magnet\u003c\/li\u003e\n\u003cli\u003eViton O-Rings\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1994-2026 Ford F-150 (9.75 in 12-bolt rear differential)\u003c\/li\u003e\n\u003cli\u003e1997-2002 Ford Expedition 5.4L\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e \u003c\/p\u003e\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLimited Lifetime Warranty\u003c\/li\u003e\n\u003cli\u003eFits the Ford 9.75-inch 12-bolt rear differential only\u003c\/li\u003e\n\u003cli\u003eNot compatible with PowerBoost Hybrid trucks\u003c\/li\u003e\n\u003cli\u003eFill plug is positioned at the factory fluid level\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PPE","offers":[{"title":"Default Title","offer_id":48816181543069,"sku":"338051300","price":296.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0645\/2504\/1821\/files\/Differential-Cover-Kit-Rear-Ford-F150-SUV-1994-2025-338051300_1_2500x_eb53885d-9489-4e75-9aae-582e9a8bc881.jpg?v=1787066570","url":"https:\/\/rudysdiesel.com\/products\/ppe-raw-cast-aluminum-rear-differential-cover-kit-for-1994-2026-ford-f-150-expedition-9-75in","provider":"Rudy's Performance Parts","version":"1.0","type":"link"}
